PRINTING-MACHINE Specication of Letters Patenti v:Patented Ang. 27, 1967.

Applicationfiled January 11,1904. Serial No. 188,588.

the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Printing- Machines, of which I declare the following to be a full, clear, and exact description.

My invention relates to improvements in printing machines and has for its object to provide an improved device for printing upon any desired work without bringing the work directly in Contact with the printing form or type, but to make use of an intermediate transfer surfacel which shall receive its impression from the original printing form and shall then transfer this impression to the work.

In the accompanying drawings forming part of 'this specification: Figure 1 represents a front elevation `of the machine. Fig. 2 represents a vertical section on the line 2 2 o'f Fig. l, taken just inside of the lefthand side frame of the machine. Fig. 3 represents a vertical section on the line 3 3 of Fig. 1, being taken just inside the right-hand side frame of the machine. Fig. 4 represents a top plan view. Fig. 5

represents a detail side elevation ofthe work carrying cylinder. Fig. 6 represents a cross section of said work carrying cylinder thrdhg'h the lineG 6 of Fig. 5; and Fig. 7 represents a section on line-7 7 of Fig. 6.

Referring to Fig. 1, the main portion of my machine is mountedbetween two upright side frames 10 and 11 which project upward ,from the basel plate 12 and in these side frames the various revoluble parts are journaled as hereinafter explained. Also extending upward from the base plate 12 is a standard 13 in which is journaled a main driving shaft 14 whicheiitends through said frames l0 and 1,1 and serves as a main driving shaft for the machine. Journaled upon this shaft 1 4 is a pulley 15 to which driving power may be.

transmitted by means of any suitable belt; and the 16a adapted to be engaged by the lateraiprojections 17 of a collar 18 splined upon the shaft 14 and capable oflateraladjustment. A lever 19 (see Fig. 4) suitably pivoted to a bracket 20 projecting laterally from the side frame 10- is formed at its inner end to straddle the collar 18, and Acarries pins 21 which project into an annular groove 22 formed in said collar 18; and thus upon the shifting of the lever 19 the collar 18 may be shifted `laterally so as to throw its projections into the aforesaid recesses 16, and thus connect the driving pulley l5 with the driving shaft 14, this being a well known form of clutch mechanism. By means of the wheel 23' fast upon the outer end of the shaft 14-, the said driving shaft may be moved independently of the driving pulley 15. l

Referring to Figs. 1 and 2 it will be seen that the driving shaft 14 has fast upon it a gear wheel 25 which meshes on its forward side with a gear wheel 26 journaled upon a sleeve surrounding the shaft 27 as hereinafter explained. This gear wheel 26 is not shown in Fig. 2 but is shown in Fig. 1 being mounted side by side with a gear wheel 28 of thersame size which wheel 28 is shown in Fig. 2. This gear wheel 28 is mounted upon the left-hand end of a sleeve which surrounds -the shaft 27 and upon the right-hand end of said sleeve is mounted a larger gear Wheel 29 carried upon a cylinder 30 which I shall hereafter call the transfer cylinder. Thus it will be seen that the gear wheels 28 and 29 are' fast to each other and rotate together but that the gear wheel 26 is journaled between them so as to move independently of the same, and therefore the continuous rotation of the gear wheel 26 by means of the main driving gear 25 will not cause the rotation of the gear wheel 29 and its transfer cylinder until i the twin gear wheels 26 and 28 are coupled together by means hereinafter to be described.

Below the transfer cylinder 30 is a second cylinder 3l of the same diameter which I shall hereinafter cally the form cylinder; and this form cylinder has fast upon it a gear wheel 32 which is in constant mesh with the gear wheel 29. This form cylinder is arranged to carry upon its periphery any desired type or any printing characters from which it is-desired to take an impression, it being obvious that any suitable devices may be used to allow this form cylinder to be readily displaced by another form cylinder bearing different'characters. The periphery of 'the aforesaid transfer cylinder 30 is made with a continuous smooth surface, the objectief this being to have the printing from thev orm`cylinder first transferred to the periphery ofths transfer cylinder and then transfer the impression from the latter cylinder to the work in the manner to be described.

In this particular type of machine I have arranged to have the work fastened or clamped upon the periphery of a work carrying cylinder 33, which work cylinder has fast upon it a\ gear wheel 34 which is in constant mesh with the 4aforesaid gear wheel 29, so that upon the rotation of said wheel 29 the work cylinder will also be rotated and the work will be rolled over the periphery of the transfer cylinder after the work has been carried into contact with the saidl periphery in the manner to be described. l I have adopted a coni struction in my present machine which will-be -morebut,v it will of coursebe understood that my machine may be used for other purposes and with but slight changes could be made, if desired, to print upon flat surfaces. This work cylinder 33 is arranged to be given a rotary movement, as before mentioned, and also to be given a bodily movement to and from the transfer cylinder 30 for the purpose of bringing the periphery of the workinto contact with the periphery of said transfer cylinder, and is also arranged with movable jaws for centering the work upon the cylinder and with revoluble clamps for clamping portions ofthe work and holding the same firmly in position on the cylinder. ln

'- order to effect these various purposes the work cylinder engaged by a toothed segment connected with an v operating lever for the pprpose of throwing the work cylinder into. contact with the transfer cylinder in a manner to be later described. Fast upon this sleeve 42 is acollar 45 (see Figs. 5 d: 7) which is eccentrically mounted on said sleeve 42 in such manner that the work cylinder will revolve about this eccentric collar when the collar is stationary but the rotation of the collar by means of the rotation of the disk 43 will cause the work cylinder to be raised and lowered toward the transfer cylinder in a well known manner. J ournaled upon the collar 45 is a sleeve 46 to which the gear wheel 34 is made fast so that upon the rotation of said gear wheel the work cylinder will rotatewith this sleeve 46 about the eccentric collar 45. J ournaled about the sleeve 46 is a large wheel 47 which is capable of a slight degree of rotary movement for the purpose of moving inward or outward the centering jaws 48 (see Fig. 7) which jaws comprise peripheral plates having inwardly extending portions in which a groove 49 is formed; and into each of these grooves there projects a c-.tnrrim 50 which is formed on the arbor of the wheel 47 the shape of these cam rims being such that upon the rotation of the wheel 47 the jaws 48 will be moved inward or outward, there being three of the jaws upon the work cylinder. Y

As already stated the work for which I particularly designed this machine is the printing of the roller indicators for cash registers, these indicators comprising a circular band of metal held in shape by any suitable spokes extending towards the center of the indicator; and in order more firmly to clamp the indicator upon the work cylinder I have provided three clamps 5I which are carried upon the collar 52 mounted to rotate upon the sleeve 46 and each clamp is provided with slot 53 so that when the indicator W, is placed Iin position upon the work cylinder the clamp may he rotated and the indicator spokes will engage the slots 53 so that the indicator will be held firmly in'position upon the work cylinder, as shown in Fig. 3.

.I will-now describe the operating lever by which the work cylinder is moved downward and upward in orderl to carry the work into and out of contact with the transfer cylinder` This operating lever 60 (see Fig. 2) is pivoted uponV a stub shaft 61 extending outwardly from the side frame 10; and the lever has a rearwardly. ex; tending segmental gear 62 whichmeshes withthe teeth 44` of the aforesaid disk 43. The operating lever lis arranged to be set into two operative positions and in order to latch the lever in each of these positions I have provided a thumb latch 63 suitably pivoted to the operating lever at 64 and carrying a plunger 65 which engages notches 66 formed in a fixed plate 67 In Fig. 2 I have shown the upward position of the lever in which the disk 43 is so rotated that the eccentric c ollar carries the axis of rotation of the work cylinder downward so that the work will be brought into contact with the transfer cylinder 30; and when the operating lever 60 is in its downward position the rotation of the disk 43 and of the eccentric collar 45 will obviously cause the work cylinder to be raised so that the work is no longer in contact with the periphery of the transfer cylinder. It will thus be evident that by shifting the operating lever from one position to the other1-can carry lthe work into or out of contact with the transfer cylinder at will; but I have also provided means controlled by 'this same lever for connecting the main driving mechanism with the transfer cylinder and also for shifting the position of the inking transfer roller and the ink supply roller all of which means, I shall now describe.

Pivoted to the lever 60 at 70 is a link 71, the lower end of which link is pivoted at 72 to the forward curved arm 73 of a rock frame 74 suspended from a transverse rock shaft 75 which extends between the silde'frames of the machine. This swinging frame 74 has a forwardly extending arm v76 on the forward end of which is an anti friction roller 77 engaging a slot 78 formed in the link 7l; and mounted at `the intermediate portion of this arm 76 is an idle pinion 79 arranged to be thrown into and out of mesh with the previously described twin gear 26 and 28 which are mounted upon the shaft 27 the pinion 79 being of width equal to the combined width of the gears 26 and 28. Thus it `will be seen that when the lever is in the upward position, as shown by Fig. 2 the idle pinion 79 will be in mesh'with these twin gears 26 and 28 whereby the gear 28 will be coupled to thc rotating gear 26 and thus the transfer cylinder together with the form cylinder and the work cylinder will all be driven by the main driving gear 25; whereas when the operating lever 60 is in its lower position the idle pinion 27 will be ont of mesh with the twin gears 26 and 28 and the gear 26 will thereforel he driven independently ol' the gear 28 and the transfer cylinder will remain at rest. v

Extendingnlownward from the rock frame 74 and on both sides of the machine just inside the side lframes are two arms 80 between which extends a shaft 8l upon which is mounted a composition inking roller 82 which for convenience I shall call the transfer inking roller. The rock frame 74 has two rearwardly extending arms 83, one on'either side of the machine and just inside the side frames, to which arms-83 are attached links 84 which are connected at their upper ends .with arms 85 extending downwardfrom the shaft 86 and between which arms 86 extends a transverse shaft 87 upon which shaft is mbunted a composition inking roller 88 which for convenience I shall call the. inking supply roller. Mounted between the side frames 10 and 11V at the top of the machine is an ink fountain 90 comprisinga shelf which is adapted to hold the ink, and the lower portion of which shelf extends downward to an ink fountain roller 91 mounted upon a transverse shaft 92. This roller 91 has a ratchet wheel 93 mounted upon the side thereof and by means of a plate 94 carrying a pawl 95 this fountain roller 91 is given a step by step movement by means of a lever 96 Vpivoted to the side frame at 97 and carrying at its lower end an anti-friction roller 98 adapted to be engaged by a lug 99 upon the gear wheel 28 so that upon each rotation of the transfer cylinder the fountain roller `91 is advanced a certain distance by means of thisratchet and pawl connection so as to bring a new inking surface into position to supply ink. Mounted upon a transverse shaft 100 is a vibrator 101 being a hard metal roller provided with any suitable device for producing a lateral movement back and forth in the direction of its axis simultaneously with its ro' tary movement, such lateral shifting movement being well known in the printing art, the purpose being more thoroughly to distribute the ink. Mounted upon transverse shafts 102 and 103 are auxiliary distributing rollers 104 and 105 r'nade of the ordinary composition material and each bearing upon the periphery of .a hard metal roller 106 mounted upon a transverse shaft 107 which roller 106 I shall for convenience denominate the main distributing roller, its purpose being to receive ink and to distribute the same through the medium of the inking transfer roller 82 to the form cylinder 31in the manner to b e described. The shafts 100, 102 and 103 which carry respectively the vibrator and the auxiliary distributing rollers 104 and 105 are situated in sockets 108 and are yieldingly held in their bearings by means of spring-pressed plungers 109, the pressure of which plungers are regulated by means of set screws 110 extending through the plates 111, and by means of these yielding bearings the respective rollers are given freedom of movement which is necessary in the use of these composition rollers of uneven surface.

From Figs. 2 and 3 it will be seen that when the operating lever 60 is in its upper position in which the work is in Contact with the transfer cylinder, the rock frame 74 is in such position that the inking transfer roller 82 is in contact with the form cylinder 31 while the inking supply roller 88 is in contact with the vibrator 101;

Whereas when the operating lever 60 is moved y,into its lower position and the work cylinder is consequently carried outof contact with the transfer cylinder as here-- tofore explained, it will be obvious that the rock frame 74 will'be swung rearwardy thereby carrying the inking transfer roller 82 into contact with the main distributing roller 106 and by means of the link 84 the inking supply roller will be moved into Contact with the fountain roller 91. Thus with the successive movements of Ithe operating lever the ink is successively transferred from the fountain roller to the vibrator, then from the vibrator to the auxiliary roller 104, and then to the main distributing roller 106, the auxiliary roller 105 assisting in the work of distributing the ink; and this movement of the operating lever also produces a successive transfer of the ink from the main distributing roller 106 to the form cylinder 31; it being apparent that the inking of the form cylinder takes place while the work is in contact with the transfer cylinder and when the work is not in contact with the transfer cylinder the* inking transfer roller is withdrawn from contact with the form cylinder. This completes the general construction of my machine for the purpose of transferring the impression from the form cylinder through the intermdiate transfer cylinder to the'work, and in order to provide for printing the edge of the work in places which will not be brought into Contact with the transfer cylinder I have provided an auxiliary v-transfer roller and a beveled roller which I shall now describe.

Journaled upon the shaft 27 (see Fig. 3) which car ries the transfer cylinder is a. forwardly extending arm 120 the forward end of which carries a frame in which is mounted a short transverse shaft 121 upon which shaft is mounted an auxiliary transfer roller 122 which is in constant contact with the transfer cylinder 30. The upper portion of this arm 120 has mounted upon it a beveled roller 123 which is in constant contact with the auxiliary vtransfer roller 122. The lower portion of thearm 120 carries a pin 124 which engages a slot 125 formed in the forward end of an arm 126 adjustably attached to an arm 127 which extends forward from the fast to the arm 127 and by means of loosening the nut 130 of this bolt the arm 126 may be adjusted in such manner as to give more or less throw to the arm 120 during the movement of the arm 127 upon the movement of the rock shaft 75. It will be apparent from this construction that when the said operating lever is moved into its upward position, the upward movement of the arm 127 will also cau'se the upward movement of the arm 120 and will therefore (larry the beveled roller upward against the Worktcylinder and the size and position of this beveled roller is such that it will engage the edge of the periphery of the work. The auxiliary transfer roller 122 is so positioned that it bears upon the outer part of the periphery of the transfer cylinder and therefore receives ink from this `portion of the trans# fer cylinder and does not conflict with the printed characters the impression of which is transferred from the form cylinder; and thus since the beveled roller is likewise in ked from this auxiliary transfer roller the result is that the edge of the work is printed in the portions not touched by the transfer cylinder. It will be apparent that when the operating lever 60 is in its lower position as heretofore explained this .beveled roller 123 will be withdrawn from contact -with the work. The use of this beveled roller is particularly important in the case such as 1 have particularly dcscribed for the use of this machine for printing roller indicators, said indicators first being coated upon their periphery with light ink or paint and then the form cylinder of my machine being constructed with matrices of the shape of the desired figures or letters so that upon the operation of the machine this form cylinder is inked over its entire periphery and when the form cylinder is rotated in contact with the transfer cylinder,

the` entire transfer cylinder will also be inked over its periphery except, of course, in those portions that have been brought in contact with the matrices and there- .fore the work when rotated in Contact with the transfer cylinder will be printed or inked over its 4entire periphery except in those blank portions correspondingsirable to have the transfer cylinder of a somewhat resilient surface such as hard rubber and .to have the wrm cylinder of a hard or metallic surface in order to get clear cutimpressions, but if it is desired to print upon a soft surface this ord er of respective hardness of the various cylinders may be reversed so that the transfer cylinder may be a hard metallic surface and the form cylinderva resilient surface.

It will be understood from the description heretofore given that in the general operation of my machin'e the forni cylinder is first put in place, containing the different characters which it is desired to print, being either of the nature of the raised type or of a smooth surface with the matrices cut away in the configurations which it isdesired to reproduce; and after the operator has thrown the operating lever into its downward position and has securely clamped the work upon the work cylinder he then throws the lever into its upper position Awhereby the transfer cylinder is connected to the main driving mechanism, the transfer inking cylinder is thrown into Contact with the form cylinder, and upon cylinder is transferred to the smooth and continuous surface of the transfer cylinder and from thence is transferred to the work. It -will be obvious from this arrangement ofthe transfer cylinder that I am enabled to print from a iia't and continuous surface and the sharp edges of the type or ofthe matrices of the form cylinder are not brought into contact with the work; and furthermore by a double arrangement of these transfer cylinders with means for bringing one into contact with the other with the work fed between the s ame I would be enabled to print upon both surfaces of the work simultaneously owingrto the fact that there would be no interstices of the type which would require a smooth and continuous platen on the opposite side of the work from the type in case the work is of'thin material such as paper. l p

Although'l have described my invention as particularly adaptable to printing these cylindrical surfaces of roller indicators for cash` registers it is of course to be understood that I do not wish in any way to be limited in the scope of my invention to the particular construction which I have described, it being evident that other various forms of construction might be usefd for similar or kindred purposes and still be Wi thin thef-scope of my inventionand by means of usingwell known devices for producinga rolling over each other ofi surfaces other than cylinders, whether the contour of these surfaces be irregular or of any regular shape, I could by use of my invention print upon any such surfaces.
